Zamioculcas zamiifolia propagation
The zz plants I started from leaf cuttings at least 6 or more months ago all have tubers but no stems or leaves yet. One of them I started at least a year ago and still nothing above ground to show for it. I don't over water them because I know, like jades, they seem to do better with a little neglect. When I do fertilize them, I use what I call worm poop, the liquid collected from my worm trays, which the rest of my plants seem to thrive on. Any ideas what I might be doing wrong?
